Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 15 August 2021 at 15:20.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon is entering ♑ Capricorn

Moon is passing first ∠4° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1958"

Lunar disc appears visually 3.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1958" and ∠1896".

Sturgeon Moon after 4 days

Next Full Moon is the Sturgeon Moon of August 2021 after 4 days on 22 August 2021 at 12:02.

Upcoming main Moon phases

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 267 / 1220

The Moon is 10 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 267 of Meeus index or 1220 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.46 days

Length of current 267 lunation is 29 days, 11 hours and 2 minutes. It is 48 minutes longer than next lunation 268 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 42 minutes shorter than the mean length of synodic month, but it is still 4 hours and 27 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠264.3°

This lunation true anomaly is ∠264.3°. At the beginning of next synodic month true anomaly will be ∠297.8°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon after perigee

1 day after point of perigee on 17 August 2021 at 09:23 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 30 August 2021 at 02:22 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 365 993 km

Moon is 365 993 km (227 418 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 404 100 km (251 096 mi).

Moon after descending node

1 day after its descending node on 16 August 2021 at 16:04 in ♐ Sagittarius, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 30 August 2021 at 05:13 in ♊ Gemini.

Draconic month

15 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.

Moon in southern standstill

At 22:24 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-25.761°. Next 14 days the lunar orbit will move in opposite northward direction to face North declination of ∠25.868° in its northern standstill point on 2 September 2021 at 00:23 in ♋ Cancer.

Syzygy in 4 days

After 4 days on 22 August 2021 at 12:02 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
